Drive-by sound check on Hushpowers --wow!
Finally got a chance to hear my '11 GT with the oft-dissed Flowmaster Hushpower axlebacks driven hard from outside the cockpit. Had my good friend Rick drive it sportingly, from a standing start next to me to a couple of aggressive runs past me. All I can say is, "Wow!" This is exactly what I wanted, a deep, powerful rumble that escalates into a roar as the rpms go up, not too loud, but definitely louder than stock. You just can't hear and appreciate it when driving, and the cursed "drone" becomes the most noticeable sound trait. The drone is reduced to darn near eliminated by (a.) disabling or removing the sound tube,(b.) loosening all the exhaust system joints and whacking with rubber mallet before tightening to proper torque specs, and (c.) laying some brush-on or adhesive sound-deadening material under the trunk carpeting.
The sound is magnificent, classic old-school V-8, and probably won't set off alarms and alert the local constabulary.
And Rick was impressed. "I can't believe I got rubber going into second gear with an automatic!" he said. He had a Shelby Cobra 350 back in the day. Welcome to the 21st Century and the new Mustang, buddy!
As always, JMO
